Hi,
My Bosch HBC84K550B goes off after 3 seconds. I removed the round glass plate on the inside top of the oven and noticed the metal rotating thing does not move. Initially I though it might be the magnetron or door switches, but now I'm really not sure. Maybe it's the inverter?
Any ideas
Thanks

All fixed. It was the fuse on top of the microwave. Cost me all of £1. It seems that the fuse controls the spinning thing inside. Anyway fixed.
